Kendall Jenner is a sought-after model now, but suffered from teenage acne so bad that it damaged her self-esteem.

Kendall, 19, said acne “ruined her life” and made her extremely self-conscious.

“Where it really impacted me was how self-conscious I became about it,” Jenner wrote on her blog. “It completely ruined my self-esteem. I wouldn’t even look at people when I talked to them. I felt like such an outcast; when I spoke, it was with my hand covering my face.”

Kendall said her three older sisters — Kourtney, Kim, and Khloe Kardashian — had also dealt with teenage acne and helped her cope.

“I was thankful we always talked about it in my family,” said Jenner. “They would help me work on my feelings about it and how I would move past that stage of my life. I remember on Christmas Eve one year, I was sitting in my bedroom upstairs crying and Kim walked in and we talked about it together — she felt so bad for me.”

Jenner said her experience with teenage acne has taught her to not care so much what others think and to be self-confident no matter what.

“Slowly, I’m working towards not caring and I’m just in so much of a better place about it all now that I’m older,” said Kendall. “I realized that it’s a part of life for some people and it doesn’t define who you are.”
